Yeast three-hybrid assays have shown that this protein binds to the stem loops within the 3'UTR of the POLB mRNA, however the exact mechanism in how this protein regulates gene expression is still to be determined. (wikipedia.org)

Applications discussed range from measurement of slow oxidative degradation of polymers and instability of hazardous industrial chemicals to detection of bacteria in urine and evaluation of the effects of drugs on parasitic worms. (wikipedia.org)

mTOR inhibitors are a class of drugs that inhibit the mechanistic target of rapamycin (mTOR), which is a serine/threonine-specific protein kinase that belongs to the family of phosphatidylinositol-3 kinase (PI3K) related kinases (PIKKs). (wikipedia.org)

Drugs that inhibit hepatic glucuronidation, such as indomethacin, nordazepam, acetylsalicylic acid (aspirin) and trimethoprim decreased the elimination rate and increased the therapeutic strength of the medication. (wikipedia.org)

Modern drug discovery involves the identification of screening hits, medicinal chemistry and optimization of those hits to increase the affinity, selectivity (to reduce the potential of side effects), efficacy/potency, metabolic stability (to increase the half-life), and oral bioavailability. (wikipedia.org)

Modern drug discovery is thus usually a capital-intensive process that involves large investments by pharmaceutical industry corporations as well as national governments (who provide grants and loan guarantees). (wikipedia.org)

Discovering drugs that may be a commercial success, or a public health success, involves a complex interaction between investors, industry, academia, patent laws, regulatory exclusivity, marketing and the need to balance secrecy with communication. (wikipedia.org)

Chemotherapy may be given with a curative intent (which almost always involves combinations of drugs), or it may aim to prolong life or to reduce symptoms (palliative chemotherapy). (wikipedia.org)

Specifically, despite the human body's endogenous receptors, hormones, and other neurotransmitters, pharmacologists utilize assays in order to create drugs that are selective, or mimic, the endogenously found cellular components. (wikipedia.org)

Many of the side effects of chemotherapy can be traced to damage to normal cells that divide rapidly and are thus sensitive to anti-mitotic drugs: cells in the bone marrow, digestive tract and hair follicles. (wikipedia.org)

Treatment with RA caused an increase in the cytotoxicity of all 3 drugs to the 2 RA-sensitive cell lines. (uni-regensburg.de)

Such advances provide researchers with the ability not only to quantify hormones and hormone receptors, but also to contribute important pharmacological information in drug development and treatment plans. (wikipedia.org)

In 1989 the United States Food and Drug Administration (FDA) approved it for use the treatment of prostate cancer. (wikipedia.org)

Based on the natural high affinity of folate for the folate receptor protein (FR), which is commonly expressed on the surface of many human cancers, folate-drug conjugates also bind tightly to the FR and trigger cellular uptake via endocytosis. (wikipedia.org)

The ligand-binding assay methodology quantified the concentration of the hormone in the test material by comparing the effects of the test sample to the results of varying amounts of known protein (ligand). (wikipedia.org)

Targeted drug therapy is advantageous because it deposits the drug at the specific location where it can be most useful in treating the disease. (wikipedia.org)

Importantly, the use of drugs (whether chemotherapy, hormonal therapy or targeted therapy) constitutes systemic therapy for cancer in that they are introduced into the blood stream and are therefore in principle able to address cancer at any anatomic location in the body. (wikipedia.org)

Combined modality chemotherapy is the use of drugs with other cancer treatments, such as surgery, radiation therapy, or hyperthermia therapy. (wikipedia.org)

The foundations for which ligand binding assay have been built are a result of Karl Landsteiner, in 1945, and his work on immunization of animals through the production of antibodies for certain proteins. (wikipedia.org)

As a direct result of these monumental findings, researchers have continued the advancement of ligand binding assays in many facets in the fields of biology, chemistry, and the like. (wikipedia.org)

Despite advances in technology and understanding of biological systems, drug discovery is still a lengthy, "expensive, difficult, and inefficient process" with low rate of new therapeutic discovery. (wikipedia.org)

Drug discovery is done by pharmaceutical companies, with research assistance from universities. (wikipedia.org)
